Q

Treatment of miscarriage?

A

Conservative

  • let it happen naturally. Can happen in a few days/weeks
  • bleeding can last for 2/3 weeks, severe bleeding or pain should only last 1-2 hrs
  • causes infection in 1 in 4 women
  • delay in all the tissue being expelled

Surgical

  • operation under GA
  • risks such as uterine perforation and infection and major bleeding

Medical

  • misoprostol vaginal pessaries (4 pessaries)
  • induces the miscarriage
  • heavy bleeding and pain
  • infection risks are low
  • 1 in 100 risk of blood transfusion due to massive haemorrhage

Q

Phases of the menstrual cycle? When does menstruation occur?

A

Follicular phase (Day 1-14)

Ovulation (Day 14)

Luteal phase (14-28)

Menstruation occurs right at the end of the cycle around day 28/day 1.

Q

Synopsis of the Hypothalamic-Pituitary-Ovarian axis?

A

Hypothalamus releases Gonadatrophin releasing hormone (GnRH) every 90mins

Anterior Pituitary releases LH and FSH

LH acts on the ovaries to stimulate Oestrogen and Progesterone production (progesterone in luteal phase)

FSH stimulates the growth of follicles in follicular stage.

Q

Synopsis of the actions of the pituitary hormones and the ovarian hormones in the menstrual cycle.

A

LH:
Rises steadily until day 14 where here is an LH surge causing the rupture of the primary follicle and release of the ovum.

FSH:
pretty stable apart from slight increase at day 14 (Oestrogen feedback)

Oestrogen:
Increase from day 5 to day 13 (produced by developing follicle) This also causes the LH surge - positive feedback.

Progesterone:
Stable until day 16 or so when the corpus luteum starts synthesising - this decreases at day 23 if the corpus luteum regresses.

Q

Hormonal changes in menopause?

Q

What does asymmetrical intrauterine growth restriction (normal head circumference with reduced abdominal circumference) suggest?

A

Placental insufficiency - If the placenta is not supplying adequate blood to the fetus the body directs prioritises brain development at the expense of the body. As a result the abdominal circumference decreases whilst the head circumference remains normal.

Q

How do you do a late pregnancy termination? When would you?

A

20-24 weeks:

3 methods:

  1. Dilatation and extraction, KCl or Digoxin to stop fetal heartbeat, then GA and removal of fetus using sopher forceps.
  2. Induction of labour with misoprostol/mifepristine/oxytocin
  3. Intra amniotic infusion of hypertonic saline and/or prostaglandin to induce contractions.

Q

Types of spontaneous miscarriage?

A

Threatened miscarriage:
- Closed cervical os with uterine bleeding <20 weeks & confirmed viable gestation.

Inevitable miscarriage:

  • Heavy bleeding clots & pain
  • Open cervical os
  • Pregnancy will miscarraige

Incomplete:
- partially expelled contents

Complete:
- Hx of bleeding and U/S has confirmed no gestation.

Missed:

  • Foetus is dead but has not ben expelled
  • (early foetal demise)
  • Early pregnancy symptoms have gone
  • Preg test may still be positive
  • Continuous brown discharge & threatened miscarriage

Recurrent:
- Three or more sequentially

Q

Physiological changes that affect insulin in pregnancy, and may cause GDM?

A

Q

Effect of pregnancy on diabetes complications (type 1)?

    - associated with maternal death
  2. diabetic nephropathy and retinopathy may deteriorate
  3. DKA may occur (should provide home ketone testing kit)

  • Only water from midnight
  • Fasting blood glucose
  • 75g glucose challenge
  • 2-hour blood glucose

GDM if fasting ≥5.6 mmol/l or 2-hour ≥7.8 mmol/l

In those with previous GDM, either early self monitoring or early OGTT (repeat 26-28 weeks if early OGTT normal).

Q

How do you manage hypoglycaemia in the pregnant woman?

A

Pretty much as you would in a non-pregnant lady

Mild (3-4mmol/L)

Administer 10-20g of fast acting glucose:

  • 150 - 200ml fruit juice
  • 3-4 heaped teaspoons dissolved in water

Moderate (2-3mmol/L)
- 1-2 cubes of dextrose gel

Severe (<2mmol/L)

  • ABCDE
  • IM glucagon 1mg
  • Consider IV glucose bolus

Check glucose level every 15mins, when >4mmol/L eat 15g of carbs - brown bread, banana, digestive biscuits

Recheck glucose again (after 15mins)

Hyperglycaemia, dehydration, ketosis, electrolyte imbalance

Lipolysis and decraesed lipogenesis = Ketone bodies and acidosis

Hyperglycaemia induced osmotic diuresis:

  • Dehydration
  • Hyperosmolarity
